Hi,

I have created a trigger and tested on the sandbox and it works fine. I implemented it on the production last night and recieved the following errors this morning.

Apex script unhandled trigger exception by user/organization: 00520000000lct9/00D200000000Aq6 UpdateToAccSetupForm: execution of AfterUpdate caused by: System.DmlException: Update failed. First exception on row 0 with id a0220000005vt34AAA; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, This category is under construction. An email notofication will be sent when available.: [] Trigger.UpdateToAccSetupForm: line 21, column 2

 I have no idea why I am getting these errors, I recieved around 4 of them, can somebody please shine a light on this for me because I thought I had mastered the trigger.

Thanks in advance.

Here is my code:

trigger UpdateToAccSetupForm on Account (after update) { //Map to store SAP number - Map key is AccountID Map<String, String> SetupFormMap = new Map<String, String>(); //Loop for each update for (Account acc : System.Trigger.new){ //If SAP Number is not Null if (acc.IF_SAP__c != null){ //Put SAP ID into map. SetupFormMap.put(acc.ID, acc.IF_SAP__c); } else{ } } //Create a list to put all records in that need updating. List<AccountSetupForm__c> recordsforupdates = new list<AccountSetupForm__c>(); //For each key that is in the map and has an AccountSetupForm for (AccountSetupForm__c aacc :[Select Id, AccountName__c, SAP_Number__c from AccountSetupForm__c where AccountName__c IN : SetupFormMap.keySet()] ){ //If the Map contains the AccountSetupForm Foreign Key if (SetupFormMap.containsKey(aacc.AccountName__c)){ //Take SAP Number from map and add to AccountSetupForm aacc.SAP_Number__c = SetupFormMap.get(aacc.AccountName__c); //Add updated AccountSetupForm record to list. recordsforupdates.add(aacc); } } //Update all AccountSetupForm records update recordsforupdates; }
